The authors present a case of parotid gland lipoma. They underline the clinical features, the unusual finding of it in the parotid lodge and the relationship with the surrounding tissues. After having shown the nosologic pattern of this neoplasm they underline the importance of the instrumental investigations by means of ET, TC and RM, that lead to a nearly sure pre-surgery diagnosis.
In a consecutive series of 600 patients scanned by CT for various spinal diseases, those with low back and sciatic pain without disc herniation were selected for study. The causes proved to be joint facet degeneration (32 cases), stenosis of the neural foramina (13 cases), stenosis of the spinal canal (13 cases), lateral recess stenosis (6 cases) and spondylolisthesis (6 cases). The predominance of joint facet pathology as the underlying cause of low back and sciatic pain in the absence of disc herniation is confirmed. CT scanning of the soft tissues as well as of the skeletal structures is crucial to the aetiological diagnosis of the condition under study and hence to the proper planning of treatment.
16 patients with hypophyseal adenoma undergoing degenerative changes, namely necrotic-cystic changes, bleeding and calcification, were subjected to CT and the resulting density values studied. The cases were verified at operation and at histological examination. Evaluation of these features, despite the limitations of the method, proved to be very useful in differential diagnosis and in the planning of treatment.
